M5 x 0.8 Thread Specification
The designation M5 x 0.8 describes the bolt's metric thread specification:
- M5 – Nominal thread diameter of 5 mm
- 0.8 – Thread pitch of 0.8 mm between adjacent threads
Parts listings for the Husqvarna BC433 and Poulan Pro PPB330 specifically identify 530016418 as “Bolt M5 X .80.”
Thread diameter and pitch are critical when replacing equipment hardware. An M5 bolt with a different pitch should not be forced into an M5 x 0.8 threaded component.
Documented Equipment Applications
The 530016418 Bolt appears in parts catalogs for select handheld outdoor power equipment, including:
- Husqvarna BC233 B
- Husqvarna BC433 B
- Husqvarna BC433 L
- Poulan Pro PPB330
- McCulloch Cabrio 433 B
- McCulloch Cabrio 433 L
- MT XLT3300 GT
- Other compatible equipment requiring 530016418
European Husqvarna-family parts documentation specifically lists the bolt in BC233 B, BC433 B, BC433 L, and McCulloch Cabrio applications.
Exact compatibility should always be verified using the complete equipment model and parts diagram.
Engine & Carburetor-Area Applications
On documented handheld equipment diagrams, 530016418 appears within the engine parts breakdown near components associated with the carburetor and intake system.
For example, a compatible equipment IPL identifies:
- 530016418 – Bolt M5 x .80
- Carburetor adapter
- Carburetor gasket
- Carburetor adjustment boot
- Choke lever
- Air filter
- Carburetor assembly
This indicates that the fastener is used in an engine-related assembly on applicable equipment.
Because its exact mounting function can vary by model, use the illustrated parts diagram for your specific machine to determine the correct installation location.
Compatible Equipment Brands
The 530016418 bolt is documented across equipment produced under several Husqvarna-family brands.
Depending on model, applications can include:
- Husqvarna
- Poulan
- Poulan Pro
- Craftsman
- McCulloch
- AYP
- Jonsered
- RedMax
- Weed Eater
An authorized Husqvarna parts dealer specifically identifies 530016418 for Husqvarna models and other Husqvarna-produced brands requiring the same part number.
This does not mean the bolt fits every product manufactured under these brands.
Common Reasons for Replacement
Replacement of the 530016418 M5 x 0.8 Bolt may be appropriate if the original fastener has:
- Been lost
- Fallen out
- Become bent
- Broken
- Developed damaged threads
- Become cross-threaded
- Developed corrosion
- Become stripped
- Sustained impact damage
- Developed a damaged head
- Become difficult to tighten correctly
- Been damaged during equipment disassembly
- Become unsuitable for reuse
Missing or damaged hardware should be replaced before operating equipment when it is required to securely retain a component.
Thread Inspection
Before installing a new bolt, inspect the mating threads for:
- Cross-threading
- Stripping
- Corrosion
- Dirt
- Debris
- Deformation
- Cracking around the mounting point
- Previous incorrect fastener installation
Installing a new OEM bolt into damaged threads may not restore a secure connection.
Bolt vs. Screw Identification
OEM terminology can vary between equipment diagrams. A threaded fastener may sometimes be described as a:
- Bolt
- Screw
- Machine screw
- Mounting bolt
- Equipment fastener
For 530016418, parts catalogs specifically identify the component as a Bolt M5 x .80.
Using the OEM part number is therefore more reliable than identifying the component based solely on generic fastener terminology.
Installation Considerations
Before installing 530016418:
- Shut off the equipment.
- Allow the engine and muffler to cool.
- Disconnect the spark plug where appropriate.
- Identify the correct bolt location using the OEM parts diagram.
- Remove the damaged or existing fastener.
- Inspect the mating threads.
- Clean debris from the mounting area.
- Position the mating components correctly.
- Start the replacement bolt carefully by hand.
- Tighten according to the applicable manufacturer's specifications.
Starting the bolt by hand helps reduce the risk of cross-threading.
Important Notes
- Verify compatibility with your exact equipment model, product number, type number, and production revision before ordering.
- Match part number 530016418 directly with your equipment's illustrated parts diagram.
- The documented description is “Bolt M5 x .80.”
- The thread specification is M5 x 0.8.
- The nominal thread diameter is 5 mm.
- Thread pitch is 0.8 mm.
- Alternate formatted part number may appear as 530 01 64-18.
- EAN is 7391736138611.
- UPC is 193028515257 according to a U.S. genuine-parts listing.
- Do not select a replacement bolt solely because another bolt is also M5 x 0.8.
- Bolts with identical thread diameter and pitch can still differ in length, head design, shoulder configuration, material, strength, finish, and intended application.
- Use 530016418 as the primary fitment reference.
- Do not force an incorrect fastener into the mounting threads.
- Cross-threading can permanently damage the mating component.
- Start installation by hand whenever practical.
- If the bolt does not thread smoothly, stop and verify alignment and thread compatibility.
- Do not overtighten the bolt.
- Follow the applicable equipment torque specification where provided.
- Inspect the mating component if the original bolt repeatedly loosens.
- Repeated loosening may indicate damaged threads, excessive vibration, improper installation, or another mechanical problem.
- Do not automatically apply thread-locking compound unless specified by the equipment manufacturer.
- The exact installation location is model dependent.
- Do not assume the bolt performs the same function on every compatible machine.
- Some current parts sellers list 530016418 as no longer available, while others still list it as in stock or special order, so availability can vary by supplier.
- This listing is for the Husqvarna 530016418 M5 x 0.8 Bolt only unless otherwise specified.
- Nuts, washers, brackets, carburetor components, housings, and other mounting hardware are not included unless explicitly stated.
- Match Husqvarna 530016418 with your equipment's OEM parts diagram before ordering to ensure proper fitment.
